Since you said "nice leather", that rules out AirTran p) and "free peanuts" might rule out SWA. So, Delta?
Edit: Just noticed "free wifi" so, my guess is off. SWA?
I guess insjould had added that one part.
Southwest!
Ah....good ole Delta irate:
SWA FTW!
Dude...I fly United for free and I avoid them if I can get there on another airline...I'd have to say, I'm more of a fan of United
